Hirschsprung Disease Genetic Study
Hirschsprung disease is a genetic condition caused by lack of nerve cells in varying lengths of the intestines. This study will investigate the complex genetic basis of the disease, which involves multiple interacting genetic factors.
Study of STIM1 Membrane Expression
The aim of this study is to determine the expression of STIM1 in the plasma membrane of lymphocytes from patients suffering from different autoimmune diseases in order to identify new pathologies of interest presenting an over-expression of STIM1PM. This would allow to initiate, following this study, research and development programs …
Liver Transplantation in Patients With CirrHosis and Severe Acute-on-Chronic Liver Failure: iNdications and outComEs
Management of ACLF is mainly supportive. The poor outcomes lead physicians to consider liver transplantation as an option, even if controversial. In sicker recipients, LT results in immediate survival, but poor medium-term survival rates in some studies. The scarcity of deceased donors obliges to maximize LT success. Alternative strategies, as …

Application of Radiomics in Breast Cancer
Little is known about the correlation between ultrasound characteristics (conventional, elastography and contrast enhanced ultrasound (CEUS) )and pathological prognostic factors in breast cancer. The aim of this study was to explore the correlation between ultrasound characteristics and pathological prognostic factors using radiomics.
Cardiac Magnetic Resonance Tissue Characterization in COVID-19 Survivors
The purpose of this study is to test if visualizing the heart with cardiac MRI/echo will be important in the understanding cardiac function and prediction of cardiopulmonary symptoms, physical effort tolerance, and outcomes in COVID-19 survivors. If successful, the research will allow us to identify the causes of lasting cardiopulmonary …
Tissue Procurement and Natural History Study of People With Non-Small Cell Lung Cancer, Small Cell Lung Cancer, Extrapulmonary Small Cell Cancer, Pulmonary Neuroendocrine Tumors, and Thymic Epithelial Tumors
Background Lung cancer is the leading cause of cancer-related death worldwide. It causes more than one million deaths every year. Researchers want to gather tissue samples from people with lung and thymic cancers to understand the disease better. This may lead to new ways to diagnose and treat it. Objective …
